β¦ Synopsis
Copper(H) mesoporphyrin IX dimethyl ester in methylcyclohesane solution shows at 77 I; a single-line ESK spectrum ascribable to an agsrcgted species. The luminescence of the a== oOre_atc is confirmed by the absorption, emission. and escitation spectra and also its yield and lifetime ;Lre compared v&h those of the monomer_

Coupling of an unpaired d electron to the porphyrin phosphorescent triplet gives rise to a YripdoubIet" and a quartet state. Luminescence from Cu porphin and Cu octdkylporphin is fargel\-tripdoublet at liquid nitrogen temperature and quartet at liquid hydrogen tempcrnture. while Cu tetrnphenylprphin
The spectroscopic aggregation number (coherence length) and physical size of the J-aggregates of anionic mesotetrakis(4-sulphonatophenyl)porphyrin (H 4 TPPS 2Γ ) are controlled by ammonium ion concentration. The contributions of absorption and scattering are determined using the extinction and reson
## Abstract A study of luminescence properties of waterβsoluble and hydrophobic porphyrin and chlorin molecules immobilized in oxidized (i.e. nonβluminescent) and asβprepared (i.e. luminescent) porous silicon (porSi) layers is carried out. It is found that the oxidized porSi matrix itself does not
